Reverse Triangle Patterns Optical Illusion

Do you see any patterns in this illustration?

Most people will find that their eyes automatically group a number of these triangles together to make patterns.

Explanation

In this optical illusion, you may see the pieces form patterns. Our eyes are constantly looking for patterns in what we see. They would rather categorize a bunch of dots as a triangle or possibly a diamond than have to deal with identifying each dot independently. In doing this, the brain frees up part of itself to look at other interesting things.
